Longitudinal Skeletal and Dental Changes in Untreated Children with Angle Class I and III Malocclusions: A Retrospective Cephalometric Cohort Study.

ABSTRACT: Background: Class III malocclusion presents complex craniofacial growth patterns, yet longitudinal evidence remains limited compared with Class I malocclusion. This study compared skeletal and dental changes in children with untreated Angle Class I and Class III malocclusions. Methods: Forty-eight untreated children (24 Angle Class I and 24 Angle Class III) from the AAOF Craniofacial Growth Legacy Collections were included. Lateral cephalograms were taken at ages 4-5 (T0), 7-8 (T1), 10-11 (T2), and 13-14 (T3). Because the radiographs originated from heterogeneous mid-20th-century X-ray equipment with unknown magnification factors, only angular measurements were used. Cephalometric tracing was conducted using WebCeph™ software with good-to-excellent intra-examiner reliability
